JOHN F. MORGAL, 0F DAYTON, OHIO, ASSIGNOR TO THE C. W. RAYMOND COMPANY,

OF DAYTON, OHIO, A CORPORATION.

BRICK-MACHINE.

To all whom it may concern Be it known that I, JOHN F. MORGAL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Brick-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in brick machines of the character in which the bricks are cut from an advancing bar of clay by means of a cutting reel.

The main object of the invention is to provide a machine of this type in which there is little or no lost motion, and which therefore has a maximum capacity for cutting bricks of entirely uniform dimensions and with no waste of material.

To this end the invention relates more specifically to an improved form of governing mechanism comprising a governor actuated by the moving column of clay from which the bricks are cut, a friction clutch and brake actuated by said governor, a cutting reel timed relatively to the moving clay bar, and gearing arranged between said clutch and the cutting reel whereby a fixed power and variable speed is transmitted to said cutting reel. The carriage which supports the platens and the cutting reel is arranged to travel forward horizontally in unison with the moving clay bar when the bricks are being cut. It is desirable that ample time be provided for the return of the platens for each succeeding length of clay bar so that a full length of bar is delivered to said platens for each cut of the reel. The reel is, therefore, driven to consume a minimum of time in cutting the brick. And, further, means are provided for lubricating the clay bar as it advances, all of which will be more fully described in connection with the accompanying drawings.

Referring more particularly to the drawings, Figure 1 is a top plan view of the brick machine constructed in accordance with my invention; Fig. 2 is a front side elevation thereof; Fig. 3 is a rear side eleva- Specification of'Letters Patent.

Throughout the specification and drawelevation of the brake portion of the governor mechanism; Fig. 9 1s a side ings, similar reference characters indicate corresponding parts.

' Referring more particularly to the drawings, 1-1 represent base rails upon which are mounted standards 22. Mounted upon the standards 22 are upper rails 3-3 which support a plurality of rollers 4. over which the upper, rim of a conveyer belt 5 passes. The belt 5 extends around pulleys 6 and 7 mounted on shafts 8 and 9 journaled in bearing 10 attached to the standards 2. The upper rim of the belt 5 receives 1 the clay bar 11 which issues from a mill 12 v and rotates the belt 5 upon. which it is supported. The width and height of the clay bar 11 is equal to the length and width of the resulting bricks. From the belt 5, the a series of individual platens 13 having upturned ends 13*. The said platens are separated a sufficient distance to permit the cutting wires to pass between the same in cutting the bricks. widths of the platens 13 are uniform and equal to the desired said platens are attached to downwardly de pending arms 14 which are secured toa stationary shaft 15 supported at its ends in side frames 16. The frames 16 are connect-f the cross members 17 and shaft 15 form a The thickness of brick, and

ed by cross members 17, and said frames 16,:

d r etlon h n carriage which is reciprocatingly mounted on the rails 11. The cross-members 17 are provided with channels which receive balls 18 which are also received by channels in the rails 1-1, thereby forming an antifriction bearing for the carriage. From what has been stated, it will be understood that the platens 13 and cutting reel are supported on a carriage which has a horizontal reciprocating movement. The side frames 16 are provided with inside flanges 19 which provide bearings for the annular side frames 20 of the cutting reel. Anti-friction bearings of any well known type may be interposed between the fianges 19 and the frames 20. The frames 20 are connected by cross bars 21 which support theouter ends of the reel wires 1 1. The inner ends of said wires are attached to rotating members 22 journaled on the shaft 15. The ends of the wires 14; may be secured by any other suitable means. The cutting reel, consisting of the annular frames .20, cross members 22 and wires 1 is rotated by gears 23 in mesh with teeth 2 1 on the annular frames 20. See Fig. 5. The gears 23 are mounted on a shaft 25 journaled in the side carriage frames 16.

Mounted on the shaft 25 on the outside of the carriage, is an elliptical gear 26 in mesh with a similar elliptical gear 27 mounted on a shaft 28 journaled in the side frames 16. See Fig. 4.. The elliptical gears 26 and 27 drive the cutting reel at a continuous but variable speed, and the timing of the gears is such that the reel travels at an increased speed when the wires 14 are passing through the clay bar, thus giving each successive length of clay bar greater time to move onto the platens than if the reel had an unvariable movement. A full length of clay bar may, therefore, be placed upon the platens for each cutting operation. The cutting reel may, therefore, be made of greater length and the machine of large capacity. The shaft 28 is connected with a counter shaft 29 journalcd in bearings 30 extending from the rails 3 -3, by the following device. See Fig. 1. Attached to said shaft 28 by means of a coupling 31 is a plate 32 which extends into a tubular member 33 attached to the shaft 29 by a coupling 34. See Figs. 12 to 15 inclusive. This connection permits the shaft 28 to move relative to the shaft 29 and to be simultaneously rotated thereby. The tubular member 33 is provided with a head 36 which receives anti-friction rollers 37 in engagement with the plate 32. The free end of the tubular connection 33 is supported by bearing 33.

The carriage supporting the cutting reel and platens travels in one direction with the clay bar, when the cutting wires are passing throughsaid clay bar, and in the opposite the platens are receiving a new length of clay bar. The carriage is moved by and with the clay bar during the cuttingoperation by the following means. flee Fig. 9. Mounted on the shaft 9 which carries the conveyor pulley 7, is a flanged wheel 38 which is of the same diameter as the pulley 7 with the double thickness of the belt added. The periphery of the wheel 38, therefore, travels at the same speed as the belt 5 and clay bar 11. Adapted to engage the periphery of the wheel 38 is a rod 40 provided with a friction face 41 of any suitable material and attached at one end to the frame 16 of the carriage. The friction face l1 isinstrumental in maintaining a suitable frictional contact between the wheel 38 and clay bar. The rod 10 is pressed in engagement with the wheel 38 by a rod 42 provided with a turnbuckle L3, and thus the carriage is moved by the clay bar, thus insuring straight and uniform bricks. The carriage is moved in the opposite direction to receive a new length of clay bar by a crank 44.. See Fig. 3. The crank ti has pin 48 and is mounted on a shaft 4-5 journaled in bearings attached to the rails 33. The shaft 45 is provided with a gear as in mesh with a gear 17 mounted on the shaft 29. The pin 18 on the crank is adapted to engage a book 19 on one end of a rod 50 pivoted at its opposite end to the carriage at When said pin 18- picks up the hooked end 4:9 of said rod, during the rotation of the shaft 45, the carriage is moved back to receive a new length of the clay bar. During this movement the friction between the clay bar 11 and the platens 13 and the friction between the wheel 48 and rod 40 is overcome'by the power applied by the crank 4A.

The counter shaft 29 is driven from a. pulley 50, or other driving means to impart constant and variable movement to the cutting reel by the following train of gears and shafting. See Figs. 1, 2 and 3. Thesaid shaft 29 carries a gear 51 in mesh with a gear 52 on a shaft 53 journaled on the rails 3-3. The shaft 53 is provided with a spiral gear 54 (shown in broken lines in Fig. 1) in mesh with a spiral gear 55 mounted on a shaft 56 journaled in bearings 57. The shaft 56 carries a brake wheel 58 and is connected with the main drive shaft 59 by a friction clutch 60. The main drive shaft 59 is journaled in bearings 61 and carries the pulley 50. The cutting reel is rotated by the above train of gearing, and to time the rotation of the reel with the movement of the clay bar which is liable to vary, the following governing means is provided. See Figs. 8, 10 and 11. The clutch 60 is adapted to be set by cams 61 and 62. The cam 61 is provided with a lever 63 while the cam 62 is provided with recesses 64 which receive a pin 65ertending from'one-of the bearings 61% there pivoted at and connected with the rock' shaft 68 by a rod 71 and a lever 72. The levers 67 and 72 extend from opposite sides of the shaft 68 and the arrangement is such that, when the shaft 68 is rocked inone direction, the clutch 60 will be set and the brake shoe 69 will be released, and when saidshaft 68 is rotated in the opposite direction, the clutch 60 is released and the brake shoe is applied. The shaft 68 is rocked by the following means: The end of said shaft opposite the levers 67 and 72 is provided with a lever 73 having a bifurcated end 74: adapted to engage a recess 75 in an annular member 76 splined to a shaft 77 journaled in bearings 78 extending from the rails 33. The shaft 77 is driven from the shaft 53 through a gear 7 9 and the gear 52. The said shaft 77 rotates at the same speed as the shaft 29, with which it is in alinement but in the opposite direction.

The annular member 76 is provided with arms 80 which are connected by links 83 to one end each of bell-crank levers 81 pivoted at 82 to a collar 83 rigidly attached to the shaft 77. The other ends of the levers 81 lie between lugs 84 extending from a disk 85 mounted on a hollow shaft or sleeve 86 which receives one end of the shaft 77 and which is journaled in one of the bearings 78. The sleeve or shaft 86 rotates in the same direction and normally at the same speed as the shaft 77 but is capable of independent movement thereof. The said sleeve orshaft 86 is driven by the conveyer belt 5 through a gear 87 mounted on the shaft 8 which carries the pulley 6 and which is in mesh with a gear 88 on the shaft 86. The sleeve or shaft 86, driven by the belt 5, and the shaft 77, driven by the pulley 50, rotate approximately in unison, and, it will be seen, that, if for any reason, such as the acceleration of the clay bar, the shaft 86 should partake of a greater speed of rotation than the shaft 77, the relative movement between the disk 85 and the shaft 77 will rock the bellcrank levers 81 to shift the annular member 76 to set the clutch 60 and to release the brake 69, thereby speeding up the cutting reel and timing the same with the speed of the moving clay bar. When the sleeve 86 pal-takes of a less speed of rotation than the shaft 77, the disk 85 will actuate the levers 81 to release the clutch 60 and to set the brake, thereby decreasing the speed of rotation of the cutting reel in conformity with the decreased speed of the moving clay bar.

The clay bar is supported and lubricated, when passing from the belt 5 to the platens 13, by the device illustrated in detail in Figs.

' cation of said pan. The

6 and 7. Rising from the rails 11 is a standard 90 which supports horizontal rails 91' upon which an oil pan 92 is slidingly mounted. The pan 92 is provided with rollers 93 which engage the clay baron their upper run. The said'rollers93 are immersed in a bath of oil on" their lower run. The

rollers 93 are instrumental in coating the contactsurfaces of'the claybar with a'ffihn of oil, thus enabling the clay bar to slide easily over the platens 13. The sides of the clay bar are lubricated by rollers 95 mounted on swinging arms 96 pivoted at 97 to the oil pan 92. The arms 96 are connected by a spring 98 which is instrumental in pressing the rollers 95 against the sides of the clay bar. The said rollers 95 may be supplied with oil by any well known means such as a fountain 99, shown in Fig. 2. The rollers 93 and 95 may be provided with a surface of felt or any other oil-carrying material to more effectually lubricate the clay bar.

The oil pan 92 is reciprocatingly mounted to permit it to lie in the center of the span when the reach between the belt 5 and the platens 13 is at its greatest length, and said pan is provided with a splash plate 100 to prevent the oil splashing during the reciprosaid pan is reciprocated by a rod 101 extending from one of the carriage side frames 16, said rod being provided with a slot 102 which receives a pin 103 on the under side of the pan 92. The reciprocation is effected by the carriage, the length of the slot .102 being such that the pan is moved half the distance of the reci rocating movement of the carriage. After the bricks are pushed off the platens 13 by each succeeding length of the moving clay bar 11, they are carried by a plate 104 to an olfbearing belt 105 which travels at 'a higher rate of speed than the belt 5, thereby separating the brick and permitting their easy removal.

While I have described my invention with some particularity, limited to parts or their arrangement which may be varied within the skill of the mechanic. But, on the contrary, I desire to claim the combination and arrangement of a governor the movement or speed of which is controlled by a moving bar of clay, a friction clutch actuated by said governor with suitable gearing between the clutch and the cutting reel for transmitting a constant force to said reel which is variable in its movement. And means whereby a direct horizontal movement is imparted to the carriage supporting the reel and platens from the moving clay bar.
